Air Lift Performance Rear Air Suspension Kit – 2009-2013 Infiniti G37 / 2009-2020 Nissan 370Z

Complete your G37 or 370Z air suspension build with the Air Lift Performance Rear Air Suspension Kit — a purpose-engineered rear air suspension solution featuring progressive-rate double-bellow air springs over high-performance monotube threaded-body shocks with 32 levels of damping adjustability. Drop up to 4.4 inches (112mm) from stock rear ride height, dial in your damping for any driving condition, and raise back to full clearance at the push of a button. Backed by Air Lift’s one-year unlimited mileage warranty and over 70 years of air suspension engineering expertise.

Key Features:

• Progressive-rate double-bellow air springs — dual-bellow design provides a larger air volume and more progressive spring rate than single-bellow designs for superior comfort and body support
• High-performance monotube threaded-body shocks — monotube construction for consistent damping performance and better heat management; threaded body for precise ride height adjustment
• 32 levels of damping adjustability — wide range of damping adjustment from comfort to performance for precise tuning across all driving conditions
• Threaded lower mounts — allow precise ride height adjustment independent of air pressure for corner balancing and stance tuning
• 4.4 inch (112mm) drop from stock — maximum rear drop capability for an aggressive, level slammed stance
• One-year unlimited mileage warranty — Air Lift Performance’s commitment to quality and long-term reliability
• Rear kit — covers the rear suspension; pair with the Air Lift Performance front kit (ALF76010) for a complete air suspension system

Performance Benefits:

• 4.4" Rear Drop: Up to 4.4 inches of rear drop from stock ride height — more than the front kit’s 3.7" — allowing a level or slightly raked stance depending on air pressure settings
• Double-Bellow Air Spring Advantage: The double-bellow design provides a larger effective air volume than sleeve-style springs, delivering a more progressive spring rate and superior ride comfort at lower pressures while maintaining excellent body support at higher pressures
• 32-Way Damping: 32 levels of damping adjustment allow precise rear damping tuning for any driving condition — soft for daily comfort, firm for canyon or track driving
• Monotube Shock Performance: Monotube construction separates oil and gas chambers for more consistent damping performance and better heat management than twin-tube designs — particularly beneficial under sustained performance driving
• Threaded Body Precision: Threaded shock body allows independent ride height adjustment for corner balancing and precise stance tuning without affecting air pressure settings
• Matched System Performance: Engineered to work in conjunction with the Air Lift Performance front kit (ALF76010) for a balanced, matched air suspension system across both axles

• Installation instructions

Installation Notes:

• Professional installation strongly recommended — air suspension installation involves suspension disassembly, air line routing, and electrical connections
• An air management system (compressor, air tank, manifold, solenoids, and controller) is required and sold separately
• Full alignment required after installation
• Route air lines away from heat sources, sharp edges, and moving components
• Torque all fasteners to Air Lift’s specified values with the suspension at ride height
• Test all air connections for leaks before returning the vehicle to service
• Pair with the front kit (ALF76010) before final alignment for a matched system setup

Double-Bellow vs. Sleeve Air Springs:

Air Lift Performance uses different air spring designs for the front and rear of the G37/370Z — sleeve-style springs up front and double-bellow springs in the rear. The double-bellow design uses two convoluted bellow sections that provide a larger effective air volume than a sleeve spring of similar dimensions. This larger volume delivers a more progressive spring rate curve and superior ride comfort at lower pressures, making it well-suited for the rear suspension where ride quality and body support under load are critical. The double-bellow design also allows the 4.4" rear drop capability — more than the front kit’s 3.7" — enabling a level or slightly raked stance depending on pressure settings.

The G37 / 370Z Platform:

The Infiniti G37 and Nissan 370Z share the FM platform and the VQ37VHR naturally aspirated V6 — one of the most celebrated sports car engines of its era. Both platforms have a passionate enthusiast following and a strong aftermarket ecosystem. A complete Air Lift Performance front and rear air suspension system transforms either platform — delivering the ability to run an aggressive slammed stance for shows and street driving while maintaining the ride height clearance needed for daily use, all with 32-way damping adjustability for genuine performance tuning capability.

Why Air Lift Performance?

Air Lift has been engineering air suspension systems since 1949 — over 70 years of expertise in air spring design, manufacturing, and application engineering. Air Lift Performance is their enthusiast-focused division, producing high-performance air suspension kits for sports cars, JDM platforms, and European performance vehicles. Their one-year unlimited mileage warranty reflects their confidence in the quality and durability of their components.

Perfect For:

• 2009–2013 Infiniti G37 owners completing a full air suspension build with the matching front kit
• 2009–2020 Nissan 370Z builds wanting adjustable rear ride height with performance-tuned damping
• Show builds requiring maximum rear drop capability with the ability to raise for daily driving
• Performance builds wanting matched front and rear 32-way damping adjustability
• Anyone completing a full Air Lift Performance air suspension system on the G37/370Z platform

Pro Tip: Install the front (ALF76010) and rear (ALF76510) kits together and set your alignment with both axles at your target ride height. This ensures the alignment is optimized for the height you actually drive at — not the factory ride height — for the best handling and tyre wear characteristics.

Note: Air management system (compressor, tank, manifold, and controller) is not included and must be purchased separately. Full alignment is required after installation. Pair with the front kit (ALF76010) for a complete air suspension system.
